Physics: Ch 24C -Heat Radiation: Test Your Knowledge (17 of 20) What is cost of Cooking with Gas?

We will calculate the cost=? to boil 1 liter of water with the initial temperature of 20 degrees C assume $1 for each “therm”, where 1 therm=100ft^3=100,000BTU.

Economicaly makes sense to keep the gas stove, as we're "buying" more than 1 hour of our lives that was otherwised spent on the solar oven by $0.006, given most people work for about $15/hour boiling 1 liter on the solar oven would be the same cost of boiling 2 500 liters, it seems to be a great deal
